[PATCH] ARM: dts: exynos5420: Add maudio power domain

[Krzysztof Kozlowski]

Add maudio power domain to Exynos 5420 DTSI file so its state could be
tracked. This actually won't power down this domain because the pl330
dmaengine driver (for adma channel) uses IRQ safe runtime PM. Thus the
patch should not introduce any functional change except of visibility of
this domain to the system.
